Tubing connections for 96AM Wash Station The following figure shows the AssayMAP Bravo tubing connections for the 96AM Wash Station. As the figure shows, the upper pump (A) is for the fill line and the lower pump (B) is for the empty line. 14 AssayMAP 96AM Wash Station Maintenance Guide

17 Installing the wash station and connecting the tubing 96AM Wash Station fill line (A) and empty line (B) A B To ensure proper chimney filling and waste emptying characteristics for the 96AM Wash Station, ensure that you use the proper tubing combination for the Pump Module. The following table gives two recommendations: one for conservative buffer usage, and one for inducing higher volume flow through the chimneys. Fill-and-empty characteristics High volume flow in chimneys (recommended) Conservative buffer usage Tubing recommendation Fill line (A) Marprene tubing, 6.4 mm (1/4- in) ID, 1.6 wt Emptying line (B) Marprene tubing, 8 mm (5/16- in) ID, 1.6 wt The 5/16- in diameter tubing is too large for the quickdisconnect fittings and the wash station ports. You use this larger tubing only in the pump head and splice it to the 1/4- in tubing to enable connections with the other fittings and wash station ports. See the following figure and table for a tubing example and a description of the tubing components. Fill line (A) Marprene tubing, 4.8 mm (3/16- in) ID, 1.6 wt Emptying line (B) Marprene tubing, 6.4 mm (1/4- in) ID, 1.6 wt AssayMAP 96AM Wash Station Maintenance Guide 15

18 Installing the wash station and connecting the tubing Tubing example and components for high volume flow in the chimneys Item Component Description 1 Source bottle Supplies the fill liquid for the wash station. 2 Waste bottle Collects the waste liquid that is pumped from the reservoir. 3 Tubing, 8- mm (5/16- in) For high volume flow in the chimneys, use the 5/16- in diameter Marprene tubing for the length of tubing in the pump head. 4 Tubing, 6.4- mm (1/4- in) The 1.4- in Marprene tubing is for the input and output tubing connections to the wash station and the source and waste bottles. The 5/16- in diameter tubing is too large for the quickdisconnect fittings and the wash station ports. So, you use a union connector (5) to splice the 5/16- in tubing to the 1/4- in tubing. 5 Connector, union Joins two sizes of tubing, such as the 5/16- in tubing to the 1/4- in tubing. 6 Quick- disconnect fitting Enables easy removal of the wash station. The quick- disconnect fittings include an automatic- close valve. Fluid can flow only if a positive connection is made. 7 Inline pump filter Removes the particulates that can clog the chimneys in the wash station way connector Enables one tube to branch into two tubes at the input and output ports on the wash station. 16 AssayMAP 96AM Wash Station Maintenance Guide

19 Testing the 96AM Wash Station Testing the 96AM Wash Station Before you start CAUTION Any time that you uninstall and reinstall the wash station, the wash station teachpoint can shift. To prevent a potential crash, verify the wash station teachpoint in all the profiles any time you reinstall the wash station. For the teachpoint verification workflow, see Required resources and workflow on page 4. Starting up the AssayMAP Bravo Platform To test the performance of the wash station, you run the Startup utility in the Protein Sample Prep Workbench. During the Startup protocol, carefully observe the fluid as it flows out of the top of the chimneys in the wash station. Ensure that the fluid flow out of the top of each chimney and the shape of the fluid dome at the top of each chimney is consistent. If fluid does not flow out of a chimney, run the Startup protocol again to remove any bubble that might be blocking the flow. If a fluid dome shape is different than the others, carefully examine the top of the chimney for irregularities. Note: Chimney irregularities can result from a collision between the head and the wash station. To start up the system: 1 Check the levels of the wash station source and waste carboys, and fill or empty as required. 2 Turn on the AssayMAP Bravo Platform, Pump Module, and the Peltier Thermal Station Controller, if included. 3 Start the Protein Sample Preparation Workbench, and open the Utility Library. 4 Open the System Startup/Shutdown utility. 5 Click Run Startup to initialize the AssayMAP Bravo Platform and accessories. WARNING When you initialize the Bravo Platform, the head and tie bar can move. To prevent injury, keep clear of the device while it is in motion. 6 During the Startup protocol, verify that all the wash station chimneys have liquid flowing through them.
